Description
6A, 2MHz, High Efficiency Synchronous Step-Down ConverterThe RT8073 is a high efficiency PWM step-down converterand capable of delivering 6A output current over a wideinput voltage range from 2.9V to 5.5V.The RT8073 provides accurate regulation for a variety ofloads with an ±1% reference voltage at room temperature.For reducing inductor size, it provides up to 2MHzswitching frequency. The efficiency is maximized throughthe integrated 50mΩ for high side, 35mΩ for low sideMOSFETs and 250μA typical supply current.The RT8073 features over current protection, frequencyfold back function in shorted circuit, hiccup mode undervoltage protection and over temperature protection.The RT8073 is available in SOP-8 (Exposed Pad) andWDFN-12L 3x3 packages.
Features
Integrated 50mΩ and 35mΩ MOSFETs 6A Output Current High Efficiency Up to 95% 2.9V to 5.5V Input Range Adjustable PWM Frequency : 300kHz to 2MHz 0.8V ±1% Reference Voltage Adjustable External Soft-Start Power Good Indicator (WDFN-12L 3x3 only) Over Current Protection Under Voltage Protection Over Temperature Protection SOP-8 (Exposed Pad) and 12-Lead WDFN Packages RoHS Compliant and Halogen Free
Typical applications
- Point-of-Load Conversions
- LCD TV
- Distributed Power Systems
- Low Voltage, High Density Power Systems
